WINDING AND REWINDING MECHANISM FOR PERFORA'IED MUSIC-SHEETS.

To all whom it may concern:

Be it known that I, FRANcIs W. DRAPER,

residing at Detroit, in the county of Wayne and State of Michigan, a citizen of the United States, have invented certain new and useful Improvements in Winding and Rewinding Mechanism for Perforated Music-Sheets, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to Winding and rewinding mechanism particularly designed for use on piano players and other automatic musical instruments, and it is the object of the invention to simplify the construction and to overcome certain defects in mechanisms heretofore used, as hereinafter set forth.

In the drawings, Figure 1 is a perspective view of one end of the tracker box, showing the winding and rewinding mechanism attached thereto; Fig. 2 is a longitudinal section through the opposite ends of the tracker box and in the lane common to the axes of both the windlng roll and the rewinding spindle.

It is usual in the construction of self-playing musical instruments to'form the tracker box in which the winding and rewinding.

rolls are journaled of wood, and it is also usual to mount the winding mechanism or some portions thereof upon the tracker box. As a consequence if there is any shrinking or swelling of the wood due to climatic changes, the relative positions of the parts of the mechanism are changed and this often interferes with the action. With the present construction, the tracker box is still formed of wood, but all the parts of the winding and rewinding mechanism as well as the winding roll and rewinding spindle are held in fixed rela tion to each other by a metallic tie which is not influenced by atmospheric conditions.

In detail, A is the tracker box containing the ported tracker bar B and the music winding roll 0. The latter is j ournaled at its opposite ends upon pins D, D, which pass through apertures in the walls a, b, of the tracker box. E is a driven rewinding spindle and F the revoluble spindle in alinement therewith, with which the opposite end of the music holding spool is engaged. For holding these parts in fixed relation to each other, I have provided at opposite ends of the tracker box the metallic strips G, G, which extend between the axes of the wind- Specification of Letters Patent.

ing roll and rewinding spindles. The pins D, D, are secured respectively to these strips G, G, the latter by being supported in an inwardly extending bushing c on the strip G, and the former by having a threaded engagement with a correspondingly threaded aperture in the strip G. The spindles E and F are secured to the strips G, G, by providing each respectively with the bushings d, (1, which form bearings for said spindles, and to further support the spindles the strips G are formed with a return bend e, at the outer ends of which are bushings forming second bearings for the spindle. Thus the spindles are journaled in bearings which always re main in fixed relation to the axis of the winding roll.

With certain constructions of winding mechanisms heretofore used, the winding roll has been driven by a gear wheel secured to one end thereof, which meshes with a pinion on a longitudinally adjustable shaft, the arrangement being such that by moving the shaft in one direction, the pinion and gear are thrown out of mesh. In the present construction, this form of drive mechanism is employed, but in order to secure it in fixed relation to the other parts, the drive shaft H is arranged substantially in the plane common to the axes of the winding roll and re winding spindles. This permits of extending the metallicstrip G so as to include a bearing for the shaft H which as shown is formed by the bushing g.

The shaft H is continuously revolved during the operation of the mechanism by a suitable drive connection (not shown). Whenever the pinion I on said shaft is in ongagement with the gear wheel J on the winding roll, the latter will be revolved, but when the shaft H is moved longitudinally to. throw said pinion and gear out ofmesh, the roll will be no longer driven. The rewinding mechanism is set in operation simultaneously with same distance from the axis of the shaft, and thus when the shaft and collar are moved by the rocking of the arm N these pins will come into engagement, with the result that the sprocket. wheel K will be driven with the shaft. The movement of the shaft which produces this result is the same as that which separates the pinion I from the gear wheel J. O is a sprocket wheel which is fixedly secured to the rewinding spindle E and this sprocket wheel is connected with the sprocket wheel K by achain indicated by the dotted lines P.

The construction just described provides for the alternate driving-of the winding roll andrewinding spindle in opposite directions; In addition to this, itis desirable to resist the movement of the rewinding spindle when actuated by the'winding of the music sheet on the winding roll, so as to hold said sheet under proper tension while passing over the tracker. This is accomplishedby providing a brake shoe Q'which is mounted upon a spring arm R and is adapted-to be pressed by the latter against a brake wheel S on-the-rewinding spindleE, thereby retarding or resisting the free rotation of the spindle. During the rewinding it is desirable to remove this resistance which is accomplished by a rod'T connected at one end to the spring arm R and at its opposite endto a crank U upon a shaftV to which the rock arm N is secured. Thus the rocking of' the arm N- will also actuate the crank U and rod T so as to separate the brake shoe Q from the wheel S during the rewinding of the spindle. The shaft V is preferably arranged'horizontally. and is journaled in'brackets W secured to the end ofthe tracker box.

For engaging and? disengaging the music holding spool, the spindles E'and F are provided with socketsfor receiving the spindles onthe spool. It is necessary for oneofthe spindles to move longitudinally to permit of this engagement and I referably make the spindle F the adjustable one. As shown, this spindle is yieldingly. pressed towards the spindle E by a spring arm'Xwhich engages a cross bore m in the spindle and moves the latter inward, a=felt washer a being placed between the spring and the bushing d.

The spindle E is preferably provided-with anadjustable end bearing formed by the threaded pin Y which is pointed atits inner end and engages with a corresponding point bearing onthe spindle. This pin Y engages a threaded bearing in the bushing f and is locked in different positions of adjustment by a thumb nutZ.

The construction as above described is exceedingly simple and one which is inexpensive to manufacture. Thus the bars G, G, can be struck up from sheet metal. with the apertures for the bushings therein, and the bushings c, d, d, f, etc., can be then secured in said apertures by upsetting the ends thereof.

What I claim as my invention is 1. The combination with a wooden tracker box, of a winding roll and rewinding spindle arranged in parallel relation and in substantially the same plane, bearings therefor, metal strips on opposite sides of said tracker box carrying and connecting all of said bearings, and holding the same in rigid relation to each other.

2. The combination with a winding roll and a rewinding spindle, of a bearing for said roll, two separated bearings for said spindle, and an integral metallic strip carrying said bearings and forming a rigid tie between said roll and spindle.

3. The combination with a winding roll and'a rewinding spindle,.of a metallic strip extendingbetween said'roll and spindle and having an integral return bent extension, and alined bearings for said spindle carried by said strip and return bent extension.

4. The combination with a winding roll and alined rewinding spindles, of a pair of return bent metallic strips, a pair or separated bearings for each of said spindles, one pair of bearings being carried by each of said strips, and a wooden tracker box upon opposite ends of which said return bent strips are mounted.

5. The combination with a tracker box, of a winding spindle revolubly mounted at one end of said box, a transversely apertured spindle at the opposite end of said box, separated bearings in which the latter spindle is slidably secured, and a spring engaging the aperture in said spindle for the purpose described.

6.. The combination with atracker box, of a winding spindle revolubly mounted at one end of said box, .a spindle at the opposite end of said box, separated bearings in which the latter spindle is slidably secured-and a single means for holding said spindle from'rotation and for; yieldably pressing the same toward said revoluble spindle.

In testimony whereofll aflix my signature in presence of two witnesses.

FRANCIS W. DRAPER.
